Thanks for the above. Maybe I misunderstood (having been pointed to ticket
22815) that I needed some way to install wxWidgets "non-universal" and yet I
was unclear how to achieve that, having not actually requested +universal
I therefore wondered whether something already-installed dependency was causing
it. That is why I uninstalled python26 and other ports. Moreover, believing it
important to try some things (so as to not be seen as asking every step) is why
I tried a manual selection of platform variants ( +darwin or +darwin_10) in
case that was the means to avoid a universal build, so thanks for pointing out
that platform selection is automatic.

could have been prevented if I had first installed zlib, expat, and libsdl

I gather that installing dependencies as +universal overrides what would have
been Snow Leopard's default behaviour (of building just x86_64 bit) such that
the resulting fat file will contain a 32-bit architecture which then allows the
creation of a 32-bit wxWidgets?
I did reinstall zlib as +universal and as a result the architecture returned by
'lipo -info /opt/local/lib/libz.dylib' is
Architectures in the fat file: /opt/local/lib/libz.dylib are: x86_64
i386
and the -arch flags in DEBUG were
-arch x86_64 -arch i386
So in the end my questions are:
1. before trying again to install wxWidgets should I *first* install as
+universal what appear to be my remaining missing wxWidgets dependencies
tiff
libpng
2. since Jyrki seems to be saying wxWidgets (2.8.9) will build only as 32-bit
(and as there seems now no +universal option), does the following achieve to
make a non-universal wxWindows?
sudo port install -d wxWIndows
3. shall I also then (to keep 32 bitness available) install +universal other
ports that I will want / need:
python26
openssl
postgresql84
4. and if I will also need py26-wxpython, is the lack of a universal variant a
problem (if I would correctly understand Snow Leopard will want to build it
x86_64 yet it will depend on a wxWidgets which will be 32-bit non-universal)?
